We are implementing new Guardian settings in the python code for damping the violin modes. Till now Guardian use to switch off damping for any of the modes rising by 1 order of magnitude. In the new settings, Guardian will just flag the following message (give below) and will continue damping them.

'mode %s is growing!! not turning off gain'

We have found that during Monday CAL sweeps (modes rise slowly over few hours) or other days whenever the modes were rung up (often the monitor levels were below 1, and they are just bouncing up and down), Guardian use to switch them off. We feel this is not necessary as those modes with their correct damping settings should be successfully damped.

I will keep on eye on the new settings (especially on Monday when Jeff. K will perform CAL sweeps) and will report the progress.

The updated VIOLIN_DAMPING.py has been committed to the svn.
